Answer is D. Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for th remaining varables
2x + 4y = 10 3x - 4y = 5 5x = 15 add the 2 rows together x = 3 substitute x = 3 into any of the two equations 2x + 4y = 10 2(3) + 4y = 10 6 + 4y = 10 4y = 4 y = 1d. (3, 1) hope this helped, God bless!
